On-off structure for liquid extraction and liquid extraction assembly

Abstract

The on-off structure comprises a liquid taking body, a one-way air inlet valve part and a sealing clack, a communicating cavity is formed in the liquid taking body, a liquid taking channel communicating to the middle of the communicating cavity is formed in one side of the liquid taking body, and an elastic reset structure is arranged on the upper portion of the sealing clack. The lower portion of the liquid taking channel extends downwards, a plug is arranged at the tail end of the liquid taking channel, a through hole is formed in the middle of the liquid taking channel, the one-way air inlet valve piece penetrates through the through hole and is in sealing fit with the sealing clack, and the sealing clack is arranged on the upper portion of the communicating cavity and enables the plug to block communication between the liquid taking channel and the lower portion of the communicating cavity when the sealing clack deforms under stress. And when the sealing flap is reset, the liquid taking channel is communicated with the lower part of the conducting cavity. The special structure of the sealing flap and the deformable and reset characteristics of the sealing flap are matched with the one-way air inlet valve part to achieve two communicating pipeline states in the liquid taking body, the structure is simple, good sealing performance can be kept in the on-off process, and the gas filling or liquid taking process is more stable and reliable when the gas filling or liquid taking device is applied.

Description

technical field [0001] The invention belongs to the technical field of liquid extraction, and particularly relates to an on-off structure and a liquid extraction assembly for liquid extraction. Background technique [0002] Oak has been used as a cork since the very beginning of wine, but opening the cork is the first big problem with drinking wine. Although the existing bottle opener solves the problem of difficulty in opening the bottle to a certain extent, a series of problems may still occur in the process of opening the bottle. Deep can cause the cork to break, and these problems can affect the mood of the wine taster. In addition, the storage of wine after opening is also a big problem. If the wine is not consumed within a certain time after opening, the wine will be in contact with the air for a long time, and the oxygen in the air will cause the polyphenols and colors in the wine that are beneficial to the human body. The components such as anthocyanins are degrade...

Problems solved by technology

[0004] In order to solve the problem that the wine fetching device in the prior art requires the gas source to be mounted on the wine fetching device all the time during the wine fetching process, the gas cylinder and the liquid fetching device are mounted under the weight of the wine bottle itself when fetching the wine, which increases the A certain burden, and the internal pipeline of the wine taking device and its switching device are relatively complicated, the cost is high, and it is not easy to maintain. This application provides an on-off structure for taking liquid and a liquid taking assembly to solve The technical deficiencies mentioned above
